One of the few memories I have of my dad, who died in 1965, is sitting as a four year old, watching Jim Clark together on the telly. Since then, I've followed F1 - and I admire Rosberg's decision. Had he stayed with the team, I think he would have had little chance to defend his crown - assuming Hamilton's reliability problems did not resurface next season. Hamilton is as clinical as a Shumacher, but as mercurial as a Senna - and the combination of that and a superb engineering package is daunting for any team mate.
